Letterman 12/14 science fair kids
 

Hey, does anyone know what that kid used to first make that glowing stuff, and then to make that amazing amount of foam? I see all sorts of applications for that stuff! :D

I didn't see the episode, but I did see the commercial... Just off the top of my head he could have made a polymer reaction with methyl methacrylate, but that sounds too hazardous for kid-stuff.

It's mystery liquid! :)

That was a great segment talking to the kid with this experiment

I was gonna post the same question. If I knew how to make that stuff, I'd quit my job and I'd be home doing that all day. I think they used a blacklight to make it glow more though. When it all pooped out of the beaker- that was great.
